Enhanced modem based carrier auto-selection algorithm

Abstract

Aspects of the present disclosure includes a method of performing enhanced auto-selection in a UE including initiating the UE having at least a first subscriber identify module (SIM) card and a second SIM card, obtaining a current ICCID associated with the first SIM card, obtaining, from a cache of the UE, a previous ICCID used in a previous connection to a previously identified carrier, determining whether the current ICCID matches the previous ICCID, in response to determining that the current ICCID does not match the previous ICCID, creating a new card information using data stored in the first SIM card, obtaining one or more selection policies, identifying a carrier based on the one or more selection policies, and connecting to the identified carrier using data stored in the second SIM card associated with the identified carrier.

 determining whether the current ICCID matches the previous ICCID so the UE is able to connect to the previously identified carrier; 
 in response to determining that the current ICCID does not match the previous ICCID, initiating an auto-select process for the UE to connect to a carrier by:
 creating a new card information using data stored in the first SIM card;
